Combustion apparatus comprising a combustion chamber with target type premixing extension



R. H. GODDARD 2,563,028 COMBUSTION APPARATUS COMPRISING A COMBUSTION CHAMBER Aug. 7, 1951 WITH TARGET TYPE PREMIXING EXTENSION Filed D90. 4, 1948 .Sia wk herein disclosed. otherwise than as set forth in the claims, but what is claimed is:

l. In combustion apparatus. a combustion chamber having a nozzle and having:r a closed inner end comprising a target-type premixing chamber extension, means to direct converging jets of two different combustion liquids toward said chamber extension and inward to a common axial focus in said extension, and means to direct jets of a third and inert liquid toward said extension and inward to a second focus which *s spaced from said common focus and which is nearer the nozzle end of said combustion chamber. Said inert liquid being vaporized by the heat in said chamber extension and thereby substantially increasing the volume of gaseous discharge from said chamber extension.

2. In combustion apparatus, a combustion chamL er having a conical inner end wall, a conical target-type premixing extension, rearwardlyfacing conical means to direct converging iets of 4 two diilerent combustion liquids rearward and inward to a common axial focus in said extension. conical means to direct jets of a third liquid rearward and inward to a second focus which is spaced from said common focus and which is nearer said combustion chamber, and means tol direct an additional portion of said third liquid in tangential jets against the conical inner end wall of said combustion chamber.
